Soudal Fix ALL High Tack White – Ultra High‑Grab Hybrid Polymer Adhesive & Sealant (290ml)

Soudal Fix ALL High Tack White is a professional‑grade, ultra high‑grab hybrid
polymer adhesive and sealant designed for instant, powerful bonding on almost all
construction materials. The very high initial tack significantly reduces or
eliminates the need for mechanical fixings, while the permanently elastic, white
sealant provides durable sealing for interior and exterior applications.

Soudal Fix ALL High Tack White is a one‑component, moisture‑curing hybrid
polymer (SMX) adhesive sealant specifically formulated for applications that demand
maximum initial grab. It adheres strongly to almost every building substrate,
including porous and non‑porous materials, often without the use of a primer.

Unlike many traditional grab adhesives, Fix ALL High Tack is solvent‑free and low
odour, making it suitable for both new build and refurbishment work in occupied
premises. Once cured, it forms a strong, permanently elastic white rubber that
accommodates movement and resists weathering, making it a reliable choice for
both internal and external construction bonding and sealing.

Typical Use Cases

• Heavy‑duty fixing of skirting, architraves and timber battens to brick, block, plaster and concrete without visible screws.
• Bonding wall panels, cladding and decorative boards in shopfitting, offices, homes and commercial interiors.
• Fixing window boards, thresholds and stair treads where strong, instant grab is needed.
• Attaching metal profiles, brackets, cable trays and trunking to masonry and concrete (non‑structural).
• Perimeter sealing and bonding around door and window frames in masonry, timber or steel openings.

Installation & Application Tips

• Surface preparation:
  • All substrates must be clean, sound and free from dust, grease, oil, loose material and old failing coatings.
  • Remove loose plaster, laitance or friable surfaces and repair significant defects.
  • Degrease metals and plastics with an appropriate cleaner; lightly abrade very smooth or glossy finishes to improve key.
• Priming:
  • Fix ALL High Tack usually adheres without primer to most common building materials.
  • On very porous, chalky or critical substrates (e.g. soft plaster, dusty blockwork), apply a suitable stabilising primer as recommended by Soudal.
• Application as an adhesive:
  • Cut the cartridge tip and nozzle to the required bead size; load into a quality sealant/adhesive gun.
  • Apply vertical beads or dots to one surface – typically at 10–20 cm centres depending on the item size and weight.
  • Press the item firmly into place to spread the adhesive and ensure full contact.
  • For very heavy items or overhead work, use temporary mechanical support or fixings until adequate cure is achieved, despite the high initial grab.
• Application as a sealant:
  • Prepare the joint using backing rod or bond‑breaker tape where necessary to create the correct joint depth and profile.
  • Gun Fix ALL High Tack into the joint, ensuring continuous contact with both sides and avoiding air pockets.
  • Tool the bead within the skin time using a wetted spatula to produce a smooth, slightly concave finish for optimal performance.
• Curing & finishing:
  • Fix ALL High Tack cures by moisture; cure rate is typically about 2–3 mm per 24 hours, depending on joint thickness, temperature and humidity (see datasheet).
  • After full cure, the white joint or bond line can usually be over‑painted with many water‑based paints (always test first).
• Clean‑up:
  • Remove uncured material with a suitable Soudal cleaner or white spirit immediately after application.
  • Cured adhesive/sealant can only be removed mechanically (cutting, scraping, sanding).
• Application conditions:
  • Can often be applied to slightly damp (but not saturated) substrates – always follow Soudal guidance.
  • Do not apply in standing water, driving rain or on frozen surfaces.

Frequently Asked Questions – Soudal Fix ALL High Tack White

1. How does Fix ALL High Tack differ from standard Fix ALL or other hybrid sealants?

While standard hybrid sealants already offer good grab, Fix ALL High Tack is
specifically formulated to deliver exceptionally high initial tack. This means:

• It can hold many items in place immediately after pressing, with minimal slip.
• Less reliance on temporary supports and fixings in many vertical applications.
• Ideal for heavy or awkward items such as panels, window boards and trims where traditional sealants may slump.

2. Can I use Soudal Fix ALL High Tack White outdoors?

Yes. Fix ALL High Tack White is designed for both interior and exterior applications.
It offers excellent UV and weather resistance, making it suitable for use on:

• External door and window frames,
• Fascia, soffit and cladding trims,
• General exterior construction bonding and sealing on suitable substrates.

Ensure correct surface preparation and avoid application during heavy rain or on
very wet, icy or contaminated surfaces.

3. Is Soudal Fix ALL High Tack suitable for structural or heavily load‑bearing fixings?

Fix ALL High Tack is a very strong construction adhesive but is typically used
for non‑structural bonding and sealing. For structural or highly load‑bearing
applications:

• Always follow the guidance of a structural engineer or system designer.
• Use appropriate mechanical fixings wherever required by Building Regulations.
• Consider the adhesive as a supplementary bonding aid unless specific test
  data and approvals allow it to be used as the primary structural bond.

4. Can I paint over Fix ALL High Tack White?

In many cases, yes. Hybrid polymer sealants like Fix ALL High Tack White are often
paintable with water‑based (acrylic) paints once fully cured. For best results:

• Allow the adhesive/sealant to fully cure before painting.
• Carry out a small test patch first, as some paints may show slower drying or a
  slight difference in sheen over the joint.
• Solvent‑based or alkyd paints may not be suitable directly on the sealant – always test or consult Soudal.

5. Can Fix ALL High Tack White be used on damp or cold surfaces?

Yes, one advantage of hybrid technology is that Fix ALL High Tack can often bond to
slightly damp and colder substrates better than many solvent‑based products.
However:

• Surfaces should not be dripping wet or water‑logged.
• Very low temperatures will slow curing and may reduce initial tack on some substrates.
• Always follow Soudal’s guidance on minimum application temperatures and substrate condition.

6. Common Uses & How to Use Soudal Fix ALL High Tack White

Common Uses:

• Fast fixing of skirtings, architraves, door linings and window boards.
• Bonding wall panels, acoustic panels and decorative cladding.
• Attaching metal or uPVC trims, cable trays, brackets and trunking.
• Perimeter sealing around window and door frames in masonry or timber.
• General construction and maintenance bonding in domestic and commercial projects.

How to Use – Step‑by‑Step:
